Abstract
PURPOSE: To eliminate a hunting in a rotary drive device by providing a displacement between a dynamic stability point of and a static stability point of a rotor with respect to a stator and setting a drive pulse duration at a time required to rotate the rotor at one magnetic pitch.
CONSTITUTION: In case that a stator 10a disposed obliquely at lower position of the dynamic stability point L2 of a rotor 5 is energized at N pole when a voltage is applied to a coil 9, a display drum 1 is rotated clockwise. Thus, as the magnetic pole S of the rotor 5 approaches the dynamic magnetic pole N, an attracting force occurs therebetween to thereby accelerate its speed. When it passes the line L2, the torque is reversely acted to be decelerated. Since the magnetic pole of the rotor 5 becomes zero at its speed at the position where it is rotated at 180°, it crosses the voltage supplied to the coil 9 to thereby stop the rotor 5 at its static stability point L1.
